As Russia Advances, NATO Considers Sending Trainers Into Ukraine

So far the United States has said no, but Gen. Charles Q. Brown Jr., the chairman of the Joint Chiefs of Staff, said on Thursday that a NATO deployment of trainers appeared inevitable. “We’ll get there eventually, over time,” he said.

For now, he said, an effort inside Ukraine would put “a bunch of NATO trainers at risk” and would most likely mean deciding whether to use precious air defenses to protect the trainers instead of critical Ukrainian infrastructure near the battlefield. General Brown briefed reporters on his plane en route to a NATO meeting in Brussels.

As a part of NATO, the United States would be obligated under the alliance’s treaty to aid in the defense of any attack on the trainers, potentially dragging America into the war.

But in February, President Emmanuel Macron of France said that “nothing should be ruled out” when it comes to sending Western troops to Ukraine. Mr. Macron has doubled down on his comment since, including after senior American diplomats asked him to stop.
